Where is the water?

[sigelitest]

Ok I am having trouble getting water through my cooling system and out the side of the boat.

I ran my titian and my razor over the weekend and had water issues with both on the razor I am using the double transom mount pick up and it is running through the motor jacket and speed controller on one port. The other is just the speed controller.

On the titian I am using the rudder pick up and it goes through the ESC and then the motor jacket.

I blew through both with my air compressor and it flowed. Could it be the angle on the rudder for Titian. I never had one do this before and now I have two that are doing it.

How do you know that there is no water flowing through the system? Can you blow through the lines with your mouth? It would be extremely rare for two boats not to have water exiting if the lines are clear.

Yep I can blow through them and there was some water in the equip that blew out when I hit it with the air compressor but I cant see a stream coming out when it drives by and the titian speed control gets real hot I modified the pickup on the razor and opened up the holes to see it that will help I also added another outlet on the razor and removed the t on the outlet. It is a castle high voltage ESC and I have the pipes split in half (there are 8 of them) on the titian I have no idea other than it may be riding so high the hole on the rudder isn’t in the water enough only the prop touches the water at times I will post a pic when I get home or check my album

Do you have two pickups ? What i read is that you have a port and starboard pick up, the port side is plumbed through the esc then to the motor and the opposite side is plumbed only to the esc? If that is the case just run one line to the motor and one to the esc. They are fighting each other. pictures would help at this point.

Just read that u have the esc cooling split on either side.

here are some pics of my setup IMG-20111024-00019.jpgIMG-20111024-00020.jpgIMG-20111024-00021.jpgIMG-20111024-00022.jpg

the rest of the picsrazor.JPGIMG-20111024-00023.jpgIMG-20111024-00024.jpg notice the 2 outlet ports one for each inlet pickup

Should I separate the motor jacket from the ESC and run the motor jacket off of the rudder, i could solder a hook on the pichup or would that create too much drag on the boat.

Anyone have pics of a prop wash setup i have an idea of what i want to do but i would like to see what everyone else does.
is this the best way to get the most water through the system?

Most of use use rudder pickups, yours is fine (although not connected in your pics). The other pickups you have may be out of the water when the boat is at full speed, they are too far away from the keel. The outlet on the motor should be as high as you can get it, not 45 degrees from the top.

Not seeing a stream of water means little as long as the lines have water in them, it is not uncollon not to see water exiting depending on the spray pattern off the hull. Overheated components are just as likely to be due to excessive amp draw or run time as not enough water cooling. How hot does the motor endbell get? How hot does the ESC get? Don't bother telling me anything except a thermometer reading, anything else (short of melted shrink) isn't very helpful.

I think part of the problem on the razor (yellow ) was the strut was pointed down too much forcing the nose down. I also only had one exit and the two water lines tied to it with a T. I added another outlet and moved the strut up. I plan on separating the motor off of the rudder and adding one more outlet. The motor was about 120 and the ESC was in the high 140 range. Unfortunately I cant run it till I get a new ESC since the controller went out and I have to ship it back to castle. The titian was a little different I am using the rudder pickup and the motor was 130 and the ESC was about 180 it was a cheap 40 dollar ESC I got form HK and it still works fine but it was so hot that the double stick tape that I stuck the BEC to it with fell off. I guess the rudder might be out of the water too much I don’t know but I had a stream coming out at one time and now I don’t.

Ps Thanks fluid for the tip on the motor exit. Makes sense so the entire motor has water around it. I wasn’t thinking

i dont know if it was mentioned but you should make sure that you cant very easily blow thorough your lines resistance is also key so the water can absorb the heat, you will want a short stream not a fountain exiting the boat
